IEA Heat Pump Programme Annex 35/13: Application of Industrial Heat Pumps (IHP/IETS)

A joint venture of the International Energy Agency (IEA) Implementing Agreements "Industrial Energy-Related Technologies and Systems" (IETS) and "Heat Pump Programme" (HPP).

The objective of the Annex was to reduce the use of energy and emissions of greenhouse gas emissions by the increased application of heat pumps in industry.

» Start date: May 2010, End date: April 2014


The publications from this annex are:

» A written full report ( Part 1 and Part 2) detailing all information
» An executive summary
» A Policy Paper
» A 2-page flyer


The objective of the Annex was to reduce the use of energy and emissions of greenhouse gas emissions by the increased application of heat pumps in industry, by
» Generating information for policy makers
» Developing information for key stake holders in industry and its supply and consulting chain and for policy makers
» Getting insight in business decision processes
» Increasing the knowledge and information about IHP’s, database and getting existing information available
» Applying new technologies and identifying the needs for technological development
» Creating a network of experts
» Finding synergy with renewable energy production to increase flexibility of the grid.

Project manager and participating countries

Germany (IZW e.V.) has been the Operating Agent. The other participating countries are Austria, Canada, Denmark, France, Japan, Korea, the Netherlands and Sweden.


The following task-sharing activities were carried out by the participants:

Task 1: Market overview

Country reports on: » Overview of the energy situation in participating countries
» Overview of the energy use in segments of industries in participating countries
» Overview of the energy use for heating and cooling in industrial, commercial and large residential buildings
» Take Annex 21 as starting point and map the developments since Annex 21 in participating countries
» Make a market overview of industrial process and component manufactures and technical state of the art of heat pumps, refrigerants and new and future developments.
» Make an overview of most significant sectors and unit operations for potential hp-application studied in one typical industrial country and extrapolate this to the participating countries:
» Temperature, levels (incl. those of waste heat)
» Capacity
» Running hours
» Ecological footprint
» Make a market overview of software and calculation models
» Analyze non-technical topics/issues (energy prices, experience, legislation etc.) and what to expect in the future

Task 2: System aspects and opportunities

»Make SWOT analyses of available software and calculation procedures for application for different sectors
»Analyze and update of existing models from Annex 21, where does the heat pump fit and how does it fit
»Use the analyses of tools and findings of task 1 to determine the gaps, needs and possibilities for new model development
»Examine the possibilities to make software available

Task 3: Apparatus technology

»Overview of the development of components and HP’s from medium sizes upwards and the need to develop new technology
»Develop technology to reduce energy costs, fossil energy consumption and CO2-emissions
»Find possibilities to integrate heat pump technology into standard process machinery
»Develop ways to avoid the Constraints related to medium and high temperature refrigerants and adapt compressors for high temperature and capacity control

Task 4: System technology and application

» Collect and analyze existing and execute new case studies and example projects, especially why the technology and the system was chosen (business cases).
» Find already running HP-systems, collect and analyze data.
» Find ways to standardize and modularize system concepts
» Get access for consultants to standard solutions
» Find easy to apply standard solutions

Task 5: Communication

Communication strategy has to be developed (target groups, objectives and means) based upon learning curves by continuous consolidation of the created content through extensive monitoring of projects
» Awareness of potential (energy conservation, greenhouse gases, eco footprint, etc.)
» Develop independent information that can be used for policy developments on energy, environmental legislation
» Give recommendation on future developments
» Execute targeted work-shops with relevant stake holders, conference presentations
» Communicate directly with manufacturers and end users
» Create a Web site with database – Best practice, overview of technologies
» Give input for training courses in relation to existing organizations
